APPARATUS FOR ELECTRIC TELEGRAPHY.

SPECIFICATION forming part of Letters Patent No. 274,652, dated March 27, 1883.

` i Applicationled September 15,1882. (No model.)

To all whom tt may concern Be it known that I, PEDRO E. PEREZ, ofthe city, county, and State of New York, have in vented a new and Im proved Method of and Ap- 4 paratus for Electric Telegraphing, of which the following is a full, clear, and exact description.

The object ot' my invention is to provide means for the correct transmission of telegraph-messages by persons unskilled in the use of ordinary transmitters, and also to provide for the transmission ot' messages more rapidly than can be done with theinstruments now in use.

Reference is to beihad to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view ofthe transmittingtable with plates shown as arranged for transmission of a message. Fig. 2is a longitudinal sectionot' the same. Fig. 3 is a cross-section ofthe table. Figs. 4 and 5 representthe movable signaling-plates. Figs. Gand? represent insulating-plates used for the formingot` spaces between the words or sentences.

The table A is to be of any suitable length and width. lts top portion is formed by a metal plate, a, which is to be supported upon suitable legs or otherwise. On the sides of the plate are raised rims b b, and at the 4ends are cross-plates c, attached by screws.

lfd are strips ot' metal,or other suitable material, which are used for holding the signaling-plates down upon the table, these strips d passing beneath the end plates, c, for that purpose.

f f are the movable signaling-plates,'oon sistin g ot' smallmetal plates or blocks, provided with transverse grooves that are filled with non-conducting material, as shown at y, so that the surface of each plate consists of alternate strips of metal and insulating material, those on each plate being arranged to correspond with a letter of the. Morse alphabet. At the end of each plate is a recess, t', tted with non-conducting material to form the proper space between the letters. These spaces t' correspond in width in all the plates.

For forming spaces between words or sentences I provide smaller plates k, which may be of glass or rubber, as shown in Fig. 6, or

of metal covered with non-conducting material, as shown-in Fig. 7.

The stylus ortransmitter (shown at D) may be of any suitable character, and, as shown, consists of a handle portion, m, otnonconducting material,`iitted at one end with a metal roller, n, to which is connected a spring, o, that receives the Wire from end pole of the electric-telegraph circuit. (Shown at p) The other end ot' the line-Wire or telegraphcircuit is connected to the metal top of the table, as shown at g, Fig. 2.

The apparatus is to be usedas follows: The signaling-platesf will be contained in a suitable receptacle, each letter by itself in the same manner asa printers case. The strips d being removed, the operator, standingbefore the table, takes the plates one by one and places them in the proper order upon the table, commenoing at one end and working toward the other end, and thus forming two or more rows ot' the plates, as may be required for the message. rI he strips cl are then put in place with their ends beneath the cross-plates c, each plate t1 resting upon the adjacent edges of the two rows of the plates, and the plates c then being screwed down the plates f will be held securely. To transmit the message, the operator takes the stylus D in his hand, and, placing its lower end upon a plate at the end of the rst row, draws the stylus over the whole row. In this operation the circuit is alternately opened and closed by the alternate conducting and non-conducting surfaces of the plates f, and the signals are thus properly transmitted to form the message, as set up. The edges of the plates cl serve as guides, against which the stylus may be moved.. It will be seen that this operation of transmitting by use ofthe stylus passing over the plates can be done very rapidly, and for receiving the message at the other end of the line an ordinary Morse register can be used, the mechanism being speeded up in order to give therequired rapidity of movement to the paper; or, it dedesired, the message may be received upon chemically-prepared"paper, as in the auto- IOO sages can be first set up or prepared Afor transmission, and then all run off at once in a short space of time; or a number of persons can be employed in the work of setting up messages while only one will be required for their transmission. The work of setting up or composing the messages can readily be performed by persons unskilled in the use of ordinary telegraphic instruments, as it requires but a small amountotl practice to become proticient in the selection and placing of the plates. Neither is a skilled operator required for the transmission of the messages. By these means the work of' transmitting messages by the .electric telegraph can be done more cheaply than heretofore.

I do not limit myselfto any special construction of the transmitting-table, nor to any spe cial form of movable plates. It is evident that in place of filling the grooves of the plates with non conducting material the grooves may be of .sufficient depth and width to serve-the same purpose of breaking the circuit.

I am aware that movable type have been used for mechanically moving a circuit-closer to transmit electric signals, the type not forming part of' the electric circuit; also, that a stylus has been used with xed alphabetplates and the message spelled out by passing the stylus over the required letters. I am also aware that in chemical telegraphs it has been proposed to use the type with a brush-stylus for producing a fac-simile ot' the type uponI chemically-prepared paper. All of these devices I disclaim.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in an electric telegraphing apparatus,of the metallic plate connected with'one pole of a line-wire or electric-telegraph circuit, a stylus connected with the 3. In a telegraphic apparatus,the combination of the removable cross-plates c `and strips d with the metal signaling-blocks and dat table, said strips resting on adjacent edges of the-blocks, as shown and described, and for the purpose specified.

4. The combination', with the table a and the metal signaling-blocksj", of the strips d, arranged crosswise of the latter, as shown and described, whereby said`blocks will be held in 'place and the stylus will be guided when drawn across the faces of the blocks, as specied.
